Design of automatic control system for anti-disaster submersible pump of coal mine

In view of problem that water dam cannot be sealed and cannot be closed while water burst occurs existed in underground drainage system, the paper proposed design scheme of automatic control system for anti-disaster submersible pump of coal mine. The system uses PLC as controller, and achieves automatic control of anti-disaster submersible pump through high-voltage power distribution cabinets, soft start cabinets, electrically operated valve distribution cabinets and various sensors. Practical application results show the effectiveness of the system.
